Hi Jason,

You need some header files  :-)

You might pick up newlib-1.8.2.tar.gz and use the headers from
there.

For my own embedded work I contruct a "crosstree" and build
the binutils, gcc and newlib components as an integral release
the same way Cygnus builds their GNUpro tool chains.  You can
get an outdated version of their script from:

ports/devel/crossm68k-devel/scripts  (this will need some
tweaking to make it work with the new components)

The distfiles you want are:

gcc-core-2.95.tar.gz  (FSF)
binutils-2.9.1.tar.gz (FSF)
newlib-1.8.2.tar.gz   (Cygnus)

gdb-4.18.tar.gz       (FSF - optional but has a useful simulator)

I use powerpc-eabi for my ${TARGET} since I'm doing
embedded development, don't know what to recommend for
yours.

I'd also recommend installing David Obriens updated GCC from
ports first and using that to build the crosstree.

Good Luck,

Jerry Hicks
